What is the name of the default namespace in Kubernetes?

• A. system
• B. default
• C. core
• D. public

Answer: (B)

Namespaces provide isolated contexts for resources, and when you don’t specify one, Kubernetes places the resource in the default namespace. The name of that namespace is default. This is the standard place for ordinary workloads unless you explicitly override it with a namespace flag or a context that uses a different namespace. You’ll often see system components living in kube-system and publicly readable resources in kube-public, but those are separate special-purpose namespaces rather than the default. The other option names listed aren’t used by Kubernetes as the default namespace, so the correct choice is the one simply named default.
